lie it known that I, J Us'rUs' A. RICKABAUGH,

a resident of Pittsburg, .in the county of Alle-l gheny 'and State of Pennsylvania, have 1 nf Im ro'vement in Carventedl'a new and useful Doors; and I do hereby dee are the following thereof.

'to bea full, clear, andA exact description My invention relates to doo'rs 'foi'.box carsv -or other structures required flush with where la sliding .door is thebody of the car or other structure.

Theobjeet of my invention is toiprovideia simplel and durable form of door in' which .the

above the opening, a door suspended from said guide .rail on a trolley traveling o n said rail, the trolley wheel having a certain 5. This may be.

. :amount of longitudinal movement ivith ref-i erence toits shaft, and a forked guiding member on said door adapted to engage a guide on the oar with a relatively close en gagement, said guide having'a rounded or curved end portion.

In the accompanying drawing Figure l is a View of a portion of the side of a car ShOW- ing my invention applied thereto, showing th loor closed; Fig. 2 is a section on the line' 2-2, Fig. 1; Fig. 3 is a like View showing the door partly open; Figs. 4: and 5 are enlarged'l details of the trolley and v,supporting rail; Fig. 6 is an enlarged detail of the locking mechanism.

Referring to the drawings .the numeral 2 designates the side of a box ear with 'the olpening 3 closed by' the door 4:, `which ciamfered or beveled along -one edge' 4%.

Above the door and extending a suitable disuide rail le angle tance beyond the o enin 3 is the 'fbrme of suita iron andy said'guide rail is provided flange 6. The guide rail 5 istapered down at one end as at 7 'Wherethe ange 6 appreaches .nearer to the body of the car. Riv- `etd orffotherwise secured to the guide rail 5 isthev angle'f'ltm 8 with .the depending flange With the l 9. The flange 9 is slightly curved or turned inwardly at the end adj acent to theV opening 3 for the purposefully hereinafter set forth.

Secured to the door et are the hangers o r vbrackets l() and ll. Trolley wheels l2 and 13 are supported by the brackets l0 and l1. These wheels 12 and 13 are grooved and travel upon the flange 6 of the guide rail 5. The trolley wheel. 12 is mounted on the shaft 14 which is supported by the bracket 10, said sliding movement of the door'ln opening after it has been drawn outwardly in the manner fully hereinafter set forth. Carried by the bracket l0 isthe guide-member ldepending flange-9 of the angle bar 8. The guide-member l5 is so secured `to the bracket l0 as to have a sli ht' pivotal motion or play yto enable it to con orm to the curved portion of the flange 9, and I said guide'member may therefore be swiveld to .the bracket l0 to be secured to thelowerface vof the guide rail,

proximity to thefguide member l5 to Vhold the door in position at that upperA left hand corner land prevent its-outward movement to any extent When said door is closed. To support vthe lower. end-of the door in its sliding movement-the ear-body is provided With the guide-brackets strip 18 is secured to the car body and astop 19 1s secured to the -outer end of said s trip. In order to .hold the door securely in place at the lower left handieorn'er to against outward movement atthatpoint, I employ the lock20. 1This lock `consists of the'arm 2.1. pivoted tothe door at 22, said arm having the downwardly projecting bolt 23 which is adapted to enter the opening 24 in the guide bracket .17.' A ystop 25- is pro.- vided to limit lthe movement- "l of the arm4 21. The arm- 2l has .the `o'pening'Q which is adapted to coincide-with the opening of the staple 27. When these openings are 1n coin# eidence With'each other the Wire ofthe car -seal may be passed through-these o enings and in thi-s manner the lock is'jseal'edi prevent its outward 'mov "which jlugs are trolley wheel being freely movable longitu. dinally of said shaft so as to provide for the saidangle being 1n Contactv with or close.

17. A wear l5, said guide member-having' theforked v portionvlG Whiehis adapted to engage the provide for this movement. Anangle l5*i may guard 105 To further secure the door in position and f guide-member bein .the flange Q and said ange being curved'at its inner endv the guide-member guides the adapted to project beyond `the 'door when closed and so prevent any outward movement of the same. f

The carmay be further provided with the ordinary lock 29 and with the handle 30.

IIn the operation of my improved door,

after the door has been unlocked the operatorggrasps the handle *30 and by simplyv p`ullv ing toward the left 'moves the door sufliciently to clear the edge 4of the car door, which movement is permitted owing to the longitudinal movement of the shaft 14 with relationV to the trolley wheel 12. As the door is chamfered, it readily. slips over .the edge ofv the opening even without being drawn outwardly. Just as soon as the door has cleared the edgel of they opening theoperatorv simply throws the door to the left 'and the'itrolley wheels travel freely along the Ouidev rail 5, so that the'do'or is moved rapidly 'and with very little exertion. lThe in engagement 'with door along the flange 9 .and the trolley wheel 12 accommodates itself to the outward movement of the door so that when the guideme'mb'er 15 reaches the ,straight portion of they flange 9 the trolley wheel 12 will be throwntoward the innerend 4of the shaft 14;' As the guide-member 15 has'a certain amount of play it can readily accommodate itself tothe shape of thev flangel9 so that there is no danger of any. binding of lthe partstointerfere with the rapid.y and easy movement of the door. I n closing the door the door is simply moved to the right and as -soon asthe guide-member15 comesV into engagement with the curvedendof the flange 9 the door falls into positionautomatically and .when the door is locked by the. Ilock 20. at its lower lefthand corner, all four cor'- easy moving form of door in which ners ofthe door are securely held against outward movement, as the lugs 2S prevent any outward movement at the' upper and lower right hand corners, and the angle 15 l prevents any undue outward movement at the upper left hand corner..

By my invention I provide a very simple l the number of parts is reduced to a minimum so that there is verylittle liability of it getting out of order.

lVhat I claim is: y

l. In a door for cars or other structures, thel combination of a' track, a door carried thereby, a wlieelon said door engaging said track, a4 shaft, said wheeliand shaft axially movable, the. one with relation to the other,

a swiveled guide -member on said door hav ing a forked portion, and a guide on said car which the forkedportion of said' guide member straddles with'a relatively close engagement, one end of said guide being orked portion which straddles the guide and closely engages the same.

In testimo y.whereof, -Iv the said .IUs'rUs A. RICK'ABAUGI'I have hereunto setmy hand. j
